10,000 patients to test if platelet-rich plasma truly relieves arthritis and tendon pain.
NCT ID NCT07231471
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will follow 10,000 adults with common joint or tendon problems—like knee arthritis, tennis elbow, or plantar fasciitis—who choose to receive a platelet-rich plasma (PRP) injection. PRP is made from a patient's own blood, spun to concentrate healing factors. Participants will report their pain and function over one year to see if the treatment helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Platelet-rich plasma (PRP) injection
- What this could lead to
- If successful, this study could show that PRP injections provide meaningful pain relief and improved function for common joint and tendon conditions.
- What could go wrong
- This is an observational registry, not a controlled trial, so results may be influenced by natural recovery or placebo effects. PRP is not yet proven to be better than standard treatments.
